An example can be seen on the heroku site. Compare the started by and latest post users for any of the topics that have more than one post:

http://forem.heroku.com/forums/1

Marcus started the following, and Bob is the latest user:
http://forem.heroku.com/forums/1/topics/10

I think it has to do with the scope methods that are all set for created_at DESC.

topic_listing.posts.first.user
link_to_latest_post(topic_listing.posts.last)
